Via the Guardian:
It was the era of the nightclub, a time when dance music took hold in the UK. But the young British Asians who came of age during the 1980s and 1990s had, on the whole, conservative parents who disapproved of their children going to sweaty nightclubs, getting drunk and hooking up with the opposite sex.
Against this repressive backdrop, something new emerged that passed largely unnoticed by the mainstream: club events where thousands of young Asians would listen to music – bhangra mainly – performed by bands and later played by DJs. These events took place not at night but during the afternoon, when those kids were thought to be at college, school or the library. And so they were christened daytimers.
"They were a national phenomenon," says Rajinder Dudrah, author of Bhangra: Birmingham and Beyond. "In Nottingham, Bradford, London, Manchester, Birmingham and Luton, kids were getting on buses to go to a club where there would be 2,000 Asians dancing away. The trick was to arrive back spotless, as if nothing had happened, so you'd live to tell the tale."
